Abstract:
Pollution created by textile dyeing operations attracts significant attention because an effluent
containing a complex mixture of colored and potentially toxic compounds can be released with
the discharged water. Developing dyes and dyeing conditions to reduce the amount of residual
dye contained in any effluent has been one of many approaches to minimize this environmental
impact. Disposal of textile effluents into nature is one of the major environmental concerns of
a textile industry. Several biological, physical and chemical methods for degradation of textile
effluents are being followed, but the real challenge is to find a method that is effective,
comparatively fast and cost effective. Industrial, agricultural, and domestic activities of
humans have affected the environmental system, resulting in drastic problems such as global
warming and the generation of wastewater containing high concentration of pollutants. As
water of good quality is a precious commodity and available in limited amounts, it has become
highly imperative to treat wastewater for removal of pollutants. In addition, the rapid
modernization of society has also led to the generation of huge amount of materials of little
value that have no fruitful use. Such materials are generally considered as waste, and their
disposal is a problem. The utilization of all such materials as low-cost adsorbents for the
treatment of wastewater may make them of some value. In this review an effort has been made
to give a brief idea about the low-cost alternative adsorbent like orange peel powder with a
view to utilizing these waste/low-cost materials in the treatment of wastewater.
